HYDRANT.

SPECIFICATION forming part of Letters Patent No. 587,364, dated August3, 189'?.

Application filed April 15,1895.

T0 all whom. it may concern:

Be it known that I, FRANK M. FARWELL, of St. Paul, Ramsey county,Minnesota, have invented certain Improvements in Hydrants, of which thefollowing is a specication.

My invention relates to improvements in hydrants, its object being toprovide independent plug or nozzle cut-offs by means of which water maybe drawn from the hydrant through one plug-opening independently of themain valve and of the other plug.

To this end my invention consists in providing for each plugopening aninterior sleeve or collar, preferably provided with a double valve-seat,which sleeve is anchored in the opening by means of soft-metal filling,so as to be fixed rigidly in place. I also provide a second sleeveslidably arranged within the first or fixed sleeve and carrying a doublevalve fitted to the seat in the fixed sleeve, whereby the plug may beopened and closed and the water shut off from around the sleeve when theplug is opened. The slidable sleeve is operated by means of a collar-nutthreaded thereon and having a groove-and-flange connection with the plugor fixed sleeve. The hose is connected directly to the slidable .sleevebeyond the nut, and the turning of the nut drives the sleeve to open orclose the plug.

My invention further consists inthe construction `and combinationhereinafter particularly described and claimed.

In the accompanying drawings, forming part of this specification, Figurel is a front elevation of a hydrant fitted with my improved attachment.Fig. 2 is a vertical central section of the hydrant through the plug,showing the valve construction, the valve being open. Fig. 3 is anenlarged sectional detail of the plug and cut-o valves, taken on line omof Fig. 2 and showing the valve closed. Fig. 4L is a cross-section ofthe same, taken on line 'y y of Fig. 3. Fig. 5 is a sectional detailcorresponding to Fig. 3 of a modified construction, and Fig. 6 is adetail of a modified form of guide for the valve-carrying arms.

In the drawings, A represents a hydrant of ordinary type, provided withthe rod 2 for operating the main cut-off valve (not shown) and havingone or more plugs 3.

Arranged within the plug-fiange 4 is the sleeve 5, provided with acircumferential rib Serial No. 545,685. (No model.)

is secured the valve 13, fitted to the innerA face of the doublevalve-seat 8. It will thus be seen thatwhen the valve is thrust inwardor into open position the water from the hydrant will pass through thespace between the standards or arms carrying the valve and thencethrough the sleeve tothe connected hose. The sleeve 9 is also fittedwith the valve 14, which is adapted when Athe sleeve is driven inward tofit to the outer face of the valve-seat. This prevents the flow of waterinto the space between the two sleeves.

In order to prevent the sleeve 9 from rotating, I provide it with studsor screws 15, which travel in grooves 16 in the inner wall of the sleeve5, as shown in Figs. 3Iand 4, or, as shown in Figs. 5 and 6, thestandards or arms -11 may be fitted to notches 17 in the flange 18between the two faces ofA the double valve-seat. In order to operate thesleeve 9 so as to open and close the valve 13, I provide the collarnut19, having outwardly-projecting studs 20, threaded upon the sleeve, andheld in engagement with the plug of the hydrant by means of the flange21, engaging a similar flange 22 upon the collar 23, threaded orotherwise sewater in the space between the two sleeves may be employed,such as a narrow vent 25 through the wall of the sleeve 5, as shown inFiO. 5.

'he valve 13 stands normally open, the water bein gpcut off from thehydrant by the clos- IOO ing of the main valve, and the plug being- Whenrequired for i valve 14E preventing the flow of water between thesleeves. While the main valve remains open, to supply a second'nozzle orfor anyA other reason'the valve 13 may be closed by screwing thecollar-nut to drive the sleeve outward, so as to shut o the flow ofwater through the plug.

I claiml. In a hydrant, the combination with its l lateral plug, of thesleeve or collarslidable in said plug, and the double valve andvalveiXed parts of said plug whereby leakage seat connection betweensaid sleeve and the l around said sleeve is prevented in both open E andclosed positions thereof.

2. In combination with a hydrant plug o-r nozzle, the lsleeve arrangedtherein, Vmeans for .slidably adjusting its position, and the doublevalve and valve-seat connection bef tween said sleeve and plug wherebyleak-age ent adjusted positions.

3. In a hydrant, the combination with its i lateral plug, ofthe sleeveor collar xed in i said plug, the slidable sleeve arranged within saidfixed sleeve, and the double valve and valve-seat connection between thefixed and l slidable sleeves.

4;. In combination with a hydrant plu-g or j nozzle, the sleeve fittedto said plug, the softi metal illing anchoring the sam-e therein., the 3slidable sleeve adj ustably arranged Ain said first sleeve, the valveand valve-seat, one car- 3 ried by said slidable sleeve and the other;

upon the fixed sleeve, and the collar having f a circumferential grooveand iiange connec- .Y

tion with said fixed sleeve `and threaded upon j,

said slidable sleeve.

5. 4In a hydrant, the combination with its 1 lateral plug, of the fixeddouble valvejseat ar- 1 ranged therein, the sliding sleeve, the valve gcarried by said sleeve and fitted to the inner g valve-seat so as toclose the plug, and the secl ond valve carried by said sleeve andadapted 5 to be seated upon the outer valve-seat when f the inner valveis open, so as to prevent leakage around the sleeve.

6. In a hydrant, the combination with the lateral plug, of thevalve-seat arranged therecarried by inwardly-projecting arms Yupon saids1eeve,and fitted to said seat to close said plug, theoppositely-arranged valve-seat in said plug, and the second valvecarried by said sleeve fitted to said second seat and adapted to cut offthe fioW of water from the hydrant around said sleeve when the firstValve is open. b i 7. In a hydrant, the combination with its` lateralplug,.of the sleeve or collar fixed Within the plug-ilange and providedwith a double valve-seat, the sleeve slidable within said fixed sleeveand carrying valves, and fitted to said seats, the one to close the plugand the other to cut ohc the flow of water between said sleeves whenthe-other valve is open.

8. In a hydrant, the combination with its lateral plug, of the sleevefixed within the flange of the plug, the double valve-seat Within saidsleeve, the second sleeve slidable within said first sleeve, the pair ofvalves carried by said second sleeve and adapted to be seated by itsmovement the one to close the plug and the other to cut off the flow-fofwater between the sleeves when the plug is open, vand theeollarhavingjournal connection with the plug, and threaded upon saidinner sleeveso as to drive the same inward or outward.

9. 4In a hydrant, the combination with its lateral plug, of the sleevefixed iu said plug and provided with a double valve-seat, the `eX-teriorly-.threaded sleeve :slidable within said iirstsleeve, the valvescarri-ed thereby adapted to be closed against their respective seats,the collar nut threaded upon said second sleeve and havingfreely-turning engagement with the plug, whereby when operated it servesto ydrive the sleeve inward or outward i according to the direction `ofits rotation.

In testimony whereof I Vafin my signature in presence of two witnesses.
